Question

a box of toys is kept at a place 100m away. How long will it take to reach the box if he runs at speed of 20m/s​

Answer 1

Given:

A box of toys is kept at a place 100m away.

To find:

Time taken to reach the box if he runs at speed of 20m/s ?

Calculation:

The time taken by the boy to reach the box of toys can be calculated by dividing the distance with the speed with which the boy travels.

$\sf \therefore \: time = \dfrac{distance}{speed}$

$\sf \implies \: time = \dfrac{100 \: m}{20 \: m {s}^{ - 1} }$

$\sf \implies \: time = 5 \: sec$

So, the time taken by the boy to reach the box of toys is 5 sec.

• Kindly note , this formula is applicable only when we consider that the boy is travelling at a uniform speed.

• This would mean that the boy is not accelerating and performing uniform motion.
